The mineral nutrients are divided into two groups:
macronutrients and micronutrients.

Macronutrients
Macronutrients can be broken into two more groups:
primary and secondary nutrients.
The primary macronutrients are nitrogen (N), phosphorus (P), and potassium (K). These major nutrients usually are lacking from the soil first because plants use large amounts for their growth and survival.

The secondary macronutrients are calcium (Ca), magnesium (Mg), and sulfur (S). There are usually enough of these nutrients in the soil so fertilization is not always needed. Also, large amounts of Calcium and Magnesium are added when lime is applied to acidic soils. Sulfur is usually found in sufficient amounts from the slow decomposition of soil organic matter, an important reason for not throwing out grass clippings and leaves.

Micronutrients
Micronutrients are those elements essential for plant growth which are needed in only very small (micro) quantities . These elements are sometimes called minor elements or trace elements, but use of the term micronutrient is encouraged by the American Society of Agronomy and the Soil Science Society of America. The micronutrients are boron (B), copper (Cu), iron (Fe), chloride (Cl), manganese (Mn), molybdenum (Mo) and zinc (Zn). Recycling organic matter such as grass clippings and tree leaves is an excellent way of providing micronutrients (as well as macronutrients) to growing plants.

Casey is a polyhybrid with quite a bit of variation between individuals... there is some indica expression there, mostly from the diesel linage.

awesome read!! thank you

I like it very much Good work. Hell I went though 2 years of JR college to get all that info and you laid it out just perfect. You an Ag teacher?

Great read,all info in one place ...Thanks head.

hi h3ad,, I hope you dont mind me posting a chart and lil info i came across.

I would like to share first the plant growth chart with few explanations regarding its content. The first thing to focus on is learning basic chemistry as starting point to better understand what is going on inside any plant and the nutrition plant process itself. I am not an expert and I am not pretending to become one in this field but good advice is learning basic stuff first about this topic if we want to understand how it works. The first thing that I learned was that any plant needs 17 elements to growth properly, so proper ratios of essentials nutrients might be applied to each type of crop depending on the growth stage, foliar and soil analysis.


The chart below shows the different types of minerals needed by a plant. Starting from the most common ones on the bottom of the chart, called natural nutrients, C,H,O,Cl which are found by the plant in the surroundings representing 98% of its requirement. The 2% left needed by the plant is classified as major nutrients, secondary nutrients and micronutrients. The last group called micronutrients accounts only for 2% out of the 2% left initially. In other words, just 0.04 units out of the 2 units are needed for any plant in order to survive this is a very tiny part but extremely essential for the plant system build up process

I wish I had something for constructive to add to this discussion! So informative, thank you very much.

Thank you very much. Been looking for the info forever.

They should pass this out at the door.

Practical, thorough, and properly delivered....the vermicompost of all foundational diagnosis guides for dummies like myself. This thread has been invaluable to me over my first year of growing. Thank you so much for taking the time a decade ago.
